Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figures 1 to 3, a fully automatic continuous cleaning device for a bag filter disclosed by the present invention is installed in a pulse back blowing type bag filter, and cooperates with the back blowing structure to realize comprehensive and continuous cleaning of the dust bag. The shell 1 of the bag filter is arranged on the upper partition 2 and the lower fixed frame 3 which are parallel to each other. There are several groups of dust-removing bags 4 arranged vertically between the upper partition and the lower fixed frame. The cleaning device of the present invention is installed on the upper Between the partition and the lower fixed frame, the structure includes a cleaning component 5, a lifting component 6, a rotating drive component 7 and a guide component 8. The cleaning component is installed around the dust bag and is parallel to the upper partition. It has multiple sets of parallel Roller brushes, and adjacent two sets of roller brushes are located on both sides of the outside of the dust bag. The lifting component is vertically arranged between the upper partition and the lower fixed frame, driving the cleaning component to lift up and down, and at the same time cooperate with the guide component for lifting and guiding. The above-mentioned rotating drive assembly controls the rotation of the roller brush. When the whole device is in use, the roller brush rotates itself while lifting and lowering, so as to realize the reciprocating cleaning of the dust bag.

Specifically, the cleaning device includes a fixed frame 501, multiple groups of roller brushes 502 installed in the fixed frame at equal intervals in parallel, and a transverse shaft 503 installed in the fixed frame and arranged in a cross with the roller brushes. It is a square or rectangular structure, set on the periphery of the dust bag. The roller brush includes a rotating shaft 504 and a brush roller 505 set on the rotating shaft. Both ends of the rotating shaft are fitted with bearings 506 in a fixed frame, so that the roller brush can realize self-rotation. It is necessary to ensure that the brush roller fits the outer surface of the dust removal bag, so that the bristles on the brush roller can deeply clean the dust bonded or clogged dust on the outer surface of the dust removal bag. The two ends of the horizontal shaft are also installed in the fixed frame with bearings. The function of the transverse axis is to drive all the roller brushes to rotate. Since the transverse axis and the roller brushes are perpendicular to each other, it is necessary to cooperate with the reversing gear assembly. The reversing gear assembly includes the first bevel gear 507 and the second bevel gear that mesh with each other Gear 508, the first bevel gear is set on the rotating shaft, and the second bevel gear is set on the transverse shaft, the cooperation of the two can convert the rotation of the transverse shaft into the rotation of the roller brush. At the same time, the end of the transverse shaft needs to protrude out of the fixed frame to be connected with the rotating driving part, and the rotating driving part drives the transverse shaft to rotate.

There can be various forms of the rotary drive, for example, the horizontal shaft is driven by a motor to rotate, or a gear and a rack can be used. Considering the dust inside, the small space and the cost, the rotation of the drive The preferred form is a gear and rack structure (as shown in Figure 3), that is, a gear 701 is installed at the end of the transverse axis, and a rack 702 is vertically arranged between the upper and lower partitions. The gear and the rack are meshed with each other. When the transverse axis rises and falls, The rack can drive the gear to rotate, so that the transverse axis can rotate.

The lifting assembly includes a screw rod 601 and a driving motor 602. Both ends of the screw rod are fixed on the upper and lower partitions with bearings, and the upper end passes through the upper partition to connect with the driving motor. In order to improve the cleaning effect by slowing down the lifting speed of the cleaning assembly, An additional reducer is arranged between the drive motor and the screw to reduce the rotation speed of the screw. The cleaning component is connected to the slider on the screw to make the rotation of the screw drive the cleaning component up and down. In this embodiment, the horizontal shaft and the screw The sliding block 603 is connected, in order not to affect the rotation of the transverse shaft, it cooperates with the bearing seat 604 and is fixed on the sliding block of the screw rod.

The guide assembly is arranged at multiple positions on the outside of the fixed frame, plays a guiding role when the fixed frame is raised and lowered, and also provides support for the fixed frame, specifically including a vertically arranged guide rail 801 and a guide rail 801 installed on the fixed frame. The guide block 802 and the guide assembly are usually arranged on the four corners of the fixed frame. Since the rack and pinion structure provided at the end of the horizontal axis can also realize the function of the guide assembly, there is no need to set an additional guide assembly at the position where the rack and pinion are set.

The lower part of the dust removal bag of the conventional bag filter is in a free suspension state. However, in the present invention, in order to ensure the cleaning effect of the brush roller during use, both ends of the dust removal bag need to be fixed, and the upper part of the dust removal bag is directly fixed on the negative pressure chamber of the dust collector. On the upper partition, or an additional upper frame is set to fix, and the lower fixing frame is set under the dust bag, so that the bottom of the dust bag can be fixed, and the lower fixing frame can also realize the rack, guide rail and screw rod. The end is fixed, and the lower fixing frame will not affect the dust on the surface of the dust-proof bag to fall into the ash bin. This structure makes both ends of the bag have stress points, so that when the brush roll is cleaned up and down, the dust-proof bag will not accumulate. At the same time, the roller brush needs to be raised and lowered to achieve reciprocating cleaning. In order to ensure the precise control of the lifting position, two sets of limit switches 9 are set on the guide rail. , the other set of limit switches is installed under the slide rail and is flush with the bottom of the dust bag. When the guide block triggers the upper limit switch, the drive motor reverses to control the descent. When the guide block triggers the lower limit switch , drive the motor to rotate forward for ascending control.

The device of the present invention can realize the automatic, continuous, and reciprocating repeated cleaning of the bag, solve the problem that the dust removal efficiency of the bag filter is greatly reduced due to dust sticking to the bag, and can clean the bag of the compressed air pulse type reverse blowing dust cleaning device. The modification of the dust collector and the cooperation of the inside and outside can significantly improve the dust removal efficiency of the bag filter and the service life of the bag, reduce the cleaning intensity and manual workload, and realize automatic continuous cleaning.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
